In chapter 12, “Hundreds would die, but not the thing they died for. ‘A man can stand up …’” Relate these final words of the book to a political event that has occurred after the American Revolution (1800s-present).

Really many conflicts post WW2 could work for this. I might consider the American involvement in Vietnam. A major theme of that war, for many people, was that the soldiers didn't know what they were fighting and dying for. Thousands of Americans died for a cause that was murky at best.
